AFC fixed/search option
"AFC fixed/search" in Zenith TVs of 1980s-'90s vintage has to do with the tuner AFC system, not the channel scan, IIRC. The search option is used if you have a video game or some other external device which does not work or works poorly with the option set to fixed. The search feature causes the tuner to search for an external unit's true output frequency, which is very often different from a broadcast or cable signal. For use with regular broadcast TV or cable, I'd leave the fixed/search option set to "fixed" and forget about it. Zenith used this option on many of its cable-ready sets of this vintage (it is on an OSD submenu on some sets, like the Sentry 2 series). The channel search is done by locating AUTO CH. SEARCH on the OSD setup menu and pressing either ADJUST key to start. The tuner will then search for and store in memory all active channels in your area or on your cable system.
Hope this helps.
Kind regards,
